That is a great introduction to EFI. Some people may ask why would you use a MAP sensor in favor of a Mass Airflow Meter. Although a Mass Airflow Meter does measure the actual amount of air going into the engine, and hence gives an accurate measurement for the ECU to determine how much fuel needs to be delivered, they can be restrictive. This can lead to a reduction of engine performance at the top engine of the engines operating RPM range. MAP Sensors on the other hand measure the amount of vacuum or pressure in the intake manifold and the ECU uses that to determine the amount of fuel to deliver. The great thing about MAP sensors is that they do not cause any restriction in the intake system. Regards, Steve http://www.wolfems.com Hi Craig. That is a great introduction to EFI.
